Having thus far explained the four types of ultimate realities and their categories, Aacariya Anuruddha now proceeds to explain, in his compendium of conditionality, the analysis of their relations as conditioning states(paccayadhammaa) and conditionally arisen states (paccayauppannadhammaa), linked by the conditioning forces(paccayasatti).

Conditioned states are phenomena (dhammaa) that arise in dependence on conditions, that is, all cittas, cetasikas, and material phenomena (except the four material characteristics, i.e. production, continuity, decay, and impermanence: these are causeless).The compendium of conditionality is twofold: 1. the method of dependent arising; and 2. the method of conditional relations. Of these, the method of dependent arising is marked by the simple happening of a state in dependence on some other state. The method of conditional relations is discussed with reference to the specific causal efficacy of the conditions.

The term "dependent arising" is a compound of pa.ticca, dependent on, and samuppaada, arising, origination. The expression is generally applied to the twelve-term formula, commonly met with in the Suttas. Abstractly stated, the principle of dependent arising is expressed by the oft-occurring dictum: "When this exists, that comes to be; with the arising of this, that arises". As applied to the twelve terms of the Sutta formula, this principle means that when any of the conditions, such as ignorance, etc., exist, then in dependence on those conditions the conditionally arisen states, such kammic formations, etc., come to be.

The method of conditional relations is the method set forth in the Pa.t.thaana, the Book of Conditional Relations, the seventh and last part of the Abhidhama Pi.taka. In contrast to the method of dependent arising, which deals only with the conditioning states and conditioned states and the structure of their arising, the method of the Pa.t.thaana also deals with the conditioning forces. A force(satti) is that which has the power to bring about or accomplish an effect. All conditioning states have their particular force, and this force enables them to cause the arising of the conditioned states.The specific causal efficacy of the conditions, according to Ledi Sayadaw, means " the special force of the conditions, that is, their efficacy in various ways," and he states that unlike the method of dependent arising, where the mere conditioning state is exhibited, the method of conditional relations is taught in full by exhibiting the special force of the conditions.
